System and method for determining air propagation data in a braking arrangement of a train

摘要

A system for determining air propagation rate through a pneumatically-controlled braking arrangement of a train, the braking arrangement having a controller for adjusting air pressure of air transmitted through a brake pipe from a lead locomotive to a rear railcar, the system including: a lead device positioned on the lead locomotive and configured to associate first time data with first air pressure data sensed in the brake pipe at a first position; a rear device positioned on the rear railcar and configured to associate second time data with second air pressure data sensed in the brake pipe at a second position; and a control device configured to determine air propagation data based at least partially upon at least one of the following: first time data, first air pressure data, the first position, second time data, second air pressure data, the second position, or any combination thereof.

1. A system for determining air propagation rate through a pneumatically-controlled braking arrangement of a train, the braking arrangement having a controller for adjusting air pressure of air transmitted through a brake pipe from a lead locomotive to a rear railcar, the system comprising:
a lead device positioned on the lead locomotive and configured to associate first time data with first air pressure data sensed in the brake pipe at a first position, wherein the first air pressure data comprises a plurality of first air pressures and the first time data comprises a plurality of first time stamps set by the lead device, each of the plurality of first time stamps associated with a respective one of the plurality of first air pressures; a rear device positioned on the rear railcar and configured to associate second time data with second air pressure data sensed in the brake pipe at a second position, wherein the second air pressure data comprises a plurality of second air pressures and the second time data comprises a plurality of second time stamps set by the rear device, each of the plurality of second time stamps associated with a respective one of a plurality of second air pressures; and a control device configured to continually or periodically determine air propagation data during normal operating conditions and based at least partially upon at least one of a sensing and an observation of a change in air pressure in the brake pipe, wherein the at least one of a sensing and an observation of a change in air pressure in the brake pipe is based at least partially upon the first air pressure data from the lead device and the second air pressure data from the rear device.
